apparatus which is generally designated iny -Mounted Within alignedpassages in the' the art by the term cylinder inold. f bearing housing` 2O are tivo pins 25, leach of A cylinder mold consists of va cylindrical which carries at one end a suitable head 26,

roll of large diameter and of a varying length; .and has upon the opposite lthreaded Vend a tion will ybe apparent from the description shown, is designated generally by the numeral suitable nut 27 through manipulation of which each pin may be firmly locked in position. Each of these pins serves as the inner member of a roller bearing, there being asso-- ciated with each of these pins an outer cylindrical roller sleeve 30 and a plurality of rollers 3l, which are positioned between each of the pins and its respective cooperating roller sleeve 30. This sleeve is adapted to directly sustain a revolving load. Any suitable type of roller .may be used, although the type shown in the drawing is preferable. Each of the pins 25 is made of suitable steel so that it will stand up during operation, while each of the roller sleeves 30 is madey of extra thickness, and of suitable steel, so that it will function to sustain the load. A very simple roller bearing is thus secured which may be readily, and completely disassembled, by remov ing the nut 27 and withdrawing the pin 25 from within the aligned passages within the bearing housing, in which it is mounted. For purposes of description, the roller bearings and the supporting bearing housing 20 are termed bearing elements.

The cylinder mold, as stated above, is mounted upon a centrally arranged shaft, each extended end 35 of which is constructed to cooperatevwith the roller bearings which support the cylinder mold in proper position. One end of the bearing housing 2O is provided with a passage 36, through which the extended end of the shaft projects into the interior of the bearing housing. That part of the end of the shaft which operates with the two roller bearings is preferably cut away, as shown by the numeral 37, to receive a sleeve 3S, which is of suitable steel. This sleeve is preferably pressed on to the cut away portion of the sha-ft, and is of such material that it will ride upon the outer sleeves 30 ofthe two roller bearings to support the weight of the cylinder mold without undue wear. Of course the sleeve 38 may be dispensed with and the shaft itself be so treated as tocooperate directly with the two roller bearings.

The opposite end of the bearing housing, from that which contains the passage 36, is provided with a hub or extension 40, within which is the passage 4l. This passage is of less'diameter than, but is coaxial with, the passage 36. Mounted upon the reduced portion 37 of the shaft is a cap 42, which is provided with an extension 43 which, when the device is inassembled position, extends into the passage 4l. This extension 43 is of less.

diameter than the passage 41, and consequently permits the shaft 35, as such alignment becomes necessary because of variations in expansion or contraction ofthe various parts, variations in the setting` of the wood walls of the trough d due to swelling' or shrinking, and because of inaccuracy in the machining of the various .20, and extends acrossthe of automatic alignment ofV parts, and the like. pensed with if desired and an extension formed directly on th0 shaft itself; but the cap is desirable since it serves to prevent the sleeve37 from sliding oil' the shaft in case it should, for any cause, become loose.

Attached to the two standards 17 is a substantially semi-circular shaped arm 45, which partly surrounds the bearing housing passage 41. This arml is provided Vwith a passage 46, which is substantially coaxial with the passager4l in the hub of the bearing housing 20. Threadedlymounted within this passage 46 is a bolt 47, which cooperates with the extension 43 and serves as a thrust receiving member, to take up the end thrust upon the shaft 35. This thrust bolt, as clearly shown by the drawing, is of materially less diameter than the passage 41., so that the housing 20'may swing freely upon its supporting'V members 19, to effect, automatically, proper alignment of the shaft with the supporting roller sleeves. `Preferably several washers or wear plates are interposed between the extension 43 and the cooperating end of the thrust member 47. As shown two metallic .plates or washers are provided, one of which, the one designated by the numeral 48, is of steel, while the other, the one designated by numeral 49, is of brass or similar material. A third washer plate is also preferably Vinterposed which,.designated by the numeral 50, is preferably of leather and serves, primarily, as va packing. Tt is not necessary that these various washers be used, although it is desirable. During ordinary operation a roller of the character described, namely, one substantially 42 inches in diameter, will rotate about twenty times a minute, and therefore the wear due to thrust is comparatively small. However, it is advisable that wear plates of this character be used. By means of this described arrangement full bearing contact is insured between the roller sleeves 30 and the wear surface of the shaft 37, due to the trunnion mount-ing of the housing 2O and the independent mounting of the thrust bolt 47. And so the bearing automatically aligns itself, and the thrust-'may be varied independent of such alignment.

A lock nut 5l is provided for maintaining the thrust member 47 in adjustment.` A `passageV 52 for receiving a lubricator is also provided.

Because of its location during use there is a tendenc bearing, which of course would cause considerable damage. In order to prevent this a sleeve 55 is secured to the shaft 35 so that it will rotate with thatshaft. Thissleeve is provided with an overhung flange 56, which extends and overhangs the cooperating end of the bearing housing 20.y A collar 57, which is att-ached to the bearing housing 20 This cap may be dis-V the 9 packing 58 is provided.

and, of course, the

by means of suitableboltsis also provided, which collar lis of greater outside s diameter than thev cooperating end tofgthe bearing housing..` Any Water fallingy upon thesleeve 55 Would'tend to be flangegdue to itsrotatiomjbut if Water should drop fromithis flange upon the bearing housing then it would fall in such place that the collar 57 would prevent its passage into the bearing housing. As a further precaution the During operation the bearing .housing is filled vvith oil up to substantially the level indicated by the numeral 60. Both of the roller bearings thus runin a bath of oil, sleeve 38 will also have its surface continuously coated With oil'as a result of its contact with the surfaces of the sleeves 30.

v`While the form of apparatus Villustrated herein constitutes a preferred embodiment of the invention, it is to be understood that the invention is not limited to this precise form', andthat changes maybe made therein Without departing from the scope of the invention which is defined in the appended claims. f f
